Re: vkernel crash?

[Mike Wolman <mike@xxxxxxxxx>]

Unfortunately this is a laptop with no serial - i was very curious when i 
read about vkernels as a more general replacement for jails so installed 
dfly on the  first free machine i could lay my hands on.  I will set up 
another box with a serial console and kernel config as you suggest to try 
to provide some useful feedback.

i have continued to try to reproduce the error - even with a fair
amount of network and disk io things were fine.

i assume no chance in the future of net booting a vkernel from iscsi san 
or will "ANVIL" provide a cleaner solution to having the vkernel/vmachine 
filesystem available should the actual machine running it die and have 
some monitoring solution to start the virtual machine on another box?
